Web17 Mar 2024 · Hexane is the most commonly used solvent. Up to one-half of the lithium is replaced with sodium in order to lower the cost of the butyllithium and increase the reactivity of the dispersion. The reaction is carried out below the boiling point of the solvent. WebSimple organolithium reagents (MeLi, PhLi, n-BuLi, sec-BuLi, t-BuLi and a few others) are usually made by the reduction of halides, normally chlorides, with lithium. The direct reaction of lithium metal with more complex substrates is difficult. However, several very effective lithium-arene reagents or catalysts (such as 4,4-di-t-
